Be it known that I, ALBERT R. GoLDnIoK,

a citizen of the United States, residing at Cleveland, in the county of Cuyahoga an State of Ohio, have invented a certain new and useful Improvement in Devices for Connecting Elevating Cables to Load Carriers, of which the following is a full, clear and exact description, reference being had to the accompanying drawings. I This invention relates to devices acflapted.

or 1nstance where the cable is to engage and lift the removable body of, an automobile truck.

The methods heretofore practiced for engaging a hoisting cradle with a load made it necessary for an operator to manually enga e the hoisting element with the load at eac point of connection. These connectmg points were often inaccessible, especially where a loaded crate was placed upon a truck where one side of the crate would be adjacent to a raised platform and the other side would be adjacent to a street. This of course involved a great deal of time and inconvenience on the part of the operator and caused the trucks to remain idle for a considerable length of time.

The essential object of my invention is to provide engaging mechanismwhich may be 0 erated from either side of aload and .1920. serial no. acacia which constitute a cradle or frame which may be supported at the corners thereof by cables 15, and adapted to lift portable crates which will be hereinafter described is provided to engage the cradle with the portable cra e. v

. The longitudinal-members 10 and 11 and the transverse members 13 and 14 of the fabricatedframe may be channelswhichmay be secured together by castings 17, one of which 1s positioned at each corner of the frame. the longitudinal members is a transverse reinforcing member 18 which serves, in addition to strengthening the frame, to provide a bearing rail 20. he fabricated frame acts as a spacer to'maintain a constant distance between the supporting cable and to support the engaging mechanism.

The corner supporting members 17, preferably castings, may be rigidly secured to the frame by rivets and are provided with suitable apertures 21 for engaging the hoisting cables. are secured to the castings are preferably above the top plane of the frame.- The bottom of the casting has an opening 22 adapted to receive the engaging hook 24, of the removable body or crate 16. An extension whic will be adapted to operate simultane-f25 may be provided on the lower portion of ously a plurality of connecting points.

. Further objects are to provide a mechanism scription which relates to the drawings.

' in the claims.

The essential characteristics are set forth In the drawings Fig. l is a side elevation of a hoisting cradle embodying the features of my invention and as shown is connected to a removable automobile body; Fig. 2 is a plan of the cradle with the accompanying mechanism; Figs..3 and 4 are details in the.

nature of sections of the engagin mechanism; Fig. 5 is an enlarged detail 0 i a corner connection.

Designating the parts by the use of refer- V ence characters, 10and 11 represent'longithe rod through the medium of the casting,

while the frame merely serves'as a spacer for these corner supporting members.

The mechanism which operates the engaging pins is as follows :-A rod 26 as shown in Fig. 4: is slidably mounted in each of the four corner supporting members and is connected to the cross rail 20 by the links 27 and 28. These links are loosely connected, preferably by pins, to the cross rail at-29 and 30, thus formin a toggle joint. The cross rail 20 is slida 1y mounted on the transverse members 13 and. 14 of the frame in bearings 29 and 30. The levers 19 pivotally mounted to the lower side of the reinforcing member 18 have their inner ends slidably connected at, 31 to the cross rail 20, while the outer ends 32 protrude Rigidly secured to the centers of d o'r removable bodies 16. Suitable mechanism The points to which the cables tudinal beams, 12 and 13 transverse beams beyond the longitudinal members 10 and 11,

and forming a handle. Guide plates 33 are rigidly secured to the longitudinal members and are provided with a guide way or slot 34 in which the levers are ada ted to move. The spring35, one end of Wl'llCh is secured to the transverse mmeber 18 and the other end to the cross rail, tends to pull the cross rail to a position shown by the dotted lines in Fig. 2. The levers 19 are normally in a positionshown by the dotted lines, while the engaging pins 26 extend across the opening 22 in the casting 17.

Assuming that the frame 1s lowered and about to be ready to engage a crate, the operator, standing on either side of the crate, will throw the levers 19 into a position shown in full line in Fig. 2. This movement causes the cross rail .to move to the right and simultaneousl withdraws the engaging pins 26 from t e outer bearing of the corner supporting members. The levers are held in this position until the frame is lowered over the grappling hooks of the crate, whereupon the levers are released and the spring 35 forces the engaging pins back to their normal position. The load may then be lifted and safel: transported.

Having thus described my inventlon, I claim 1. In a device of the class descrlbed, the combination with a frame of means for engaging a plurality of hoisting elements with a load and means rojecting laterally from the frame for simuqtaneously .operatin the said engaging means from either si e of the load.

2. In a device of the class described, the combination with a frame dependlng from a plurality of hoisting cables arranged in the form of a rectangle, of means operable in a substantially horizontal plane for engaging the hoisting elements with a load, and means for simultaneously operatmg the said engaging means from either side of the load.

3. In a device of the class described, the combination with a substantially rectangular frame of laterally shiftable members mounted on said frame and adapted to engage a load, said members being operable in a horizontal plane, and means for simul-, taneously moving said members into and out of engagement with the load.

4.
